RE: [Repeater-Builder] Re: Diamond X500
I think the problem with the X-500's is they are already too tight. I have experience with 3 of them and was not too impressed. One was waterproofed at all joints with industrial Dow silicone rubber and cleaner it was up a couple of years and when taken down and taken apart it was apparent moisture had either migrated through the fiberglass or as I suspect water vapor in the air just condensed on the inside of the radome due to differing temperatures between inside and outside of the radome (dew point) kind of like when you see condensation forming on your windows in the winter time. I suspect the radome chamber is just too tight and does not allow enough ventilation to dissipate the condensation once it has formed. That and the stupid foam water sponges those io-dots put in there. I think the fix would be to drill a hole up buy the top (and or bottom) put a cap so water cant get back in and paint the thing black so you would get some solar help in drying it out. Or take the antenna out of the radome and put it in a station master shell.

[Repeater-Builder] Re: Diamond X500
You're right Steve I left out the part about the chambers being on a timer and alternating. Here is what I found, 1. the folks that put up the scaffold,..the kind that hangs off the side of the roof, had hit the hard line and loosened it from the Connector at the antenna, I re made the conector. 2. I found water inside the connector likely from #1 above. 3. The antenna had a small amount of moisture inside, not enough to pour out but enough to get the lower Foam wet. All joints are taped with fusing silicone rubber tape and over taped with 1 1/2 inch electrical tape. Still a little reflected but I plan to go back after it has a while to dryout and re check it, and solder jumpers around the screw connections inside. 73 AC0Y --- In Repeater-Builder@yahoogroups.com, "Steve Grantham" <[EMAIL PROTECTED]> wrote: > Coy, > > There ya go!

Re: [Repeater-Builder] Re: Diamond X500
Coy, There ya go! I thought it was probably a short transmission line since you said something about throwing the antenna off the roof. (he he!) If you do pressurize it, think about using a UV resistant air line.. and not more than a couple of PSI would seem to be enough.. Funny thing about all that silica gel that you see in new consumer electronics packaging.. it's always white.. That's because it's full of moisture. For the silica gel to do any good, it has to be dried. Sure.. you can bake it in the oven or in a toaster oven to make it nice and dark.. but after a while it would turn pinkish and continue to lighten up. Dehydrators like the one you mention will dry the silica gel in the chambers after they have dehydrated the air. This is why they have two chambers, and alternate between them.

RE: Spam:[Repeater-Builder] Re: Diamond X500
Coy, X-500's are awesome, I have one on my repeater as a receive antenna and an X-50 as transmit (no duplexer, yea!) X-50's and 500's are frequently used as repeater antennas. I have a friend, K4HAT, who uses a bunch of them on a linked system on the Outer Banks of North Carolina where conditions are some of the harshest imaginable.

Hi Steve, I'm going up to the site Sunday and I will likely not pressureize it, But I will be thinking about the suggestion for a good while. I would consider sense the half inch hardline is only thirty feet long to the sky hook, running a small airline to it and using a aquerium (?) pump to pressurize it. BUT I Will likely use some Scotch brand tape that I have that "fuses" to it self to water proof the fiber glass joints after drying it out with a trusty hair dryer. I wish I had about 5 pounds of "Silica JELL". Oh, while I was consulting for ANDREW Corp, some years ago I had a chance to take a look at their sweet little "HELIAX" pressureizer. It had a small GATES compresser mounted on a chassis and sucked air in through two chambers of "Silica Jell" and pumped it into the hard line. It worked really well. 73 AC0Y --- In Repeater-Builder@yahoogroups.com, "Steve Grantham" <[EMAIL PROTECTED]> wrote: > Coy.. I was just joking..

[Repeater-Builder] Re: Diamond X500
Hey Coy, I have a Diamond X-3200A that was used for my repeater antenna till I got a DB-420...now it is my remote base antenna. When the antennas were changed out we took it apart and to our amazement it was like poured out a pitcher of water on the ground (and this was before the hurricanes came thru GA ;-). I just didn't know. I sealed up that antenna to the hilt when it went up. Drain holeswhat drain holes ;-) Have you pulled the guts out of it yet? I wonder how the foam is holding up on the inside of the radone? You folks got enough water in Orlando to fill that radone up 2 times! A local ham here (thanks Darryl 8-) also did a mod on soldering the connections of the inside copper wire where it joins together. Comes loose sometimes with enough whipping action. Check those cap.s at the bottom too for it's connection. Good Luck, Robert Hi Gang, Anyone know anything about keeping water out of a Diamond X500 antenna for a repeater use, Or any other suggestions, Short of heaving it off the side of the building. 73 AC0Y Speed up your surfing with Juno SpeedBand.

Re: [Repeater-Builder] Re: Diamond X500
Coy, are you sure it's an Diamond X500? All the Diamond antennas I have messed with have weep holes right in the bottom near the connector which is one of their better options over some of the competition. Other knock off antennas don't seem to have them. Double check they aren't covered if they exist at all. Good luck! 73, Tony W4ZT At 10:24 PM 10/15/2004, you wrote: >Coy.. I was just joking..

Re: [Repeater-Builder] Re: Diamond X500
Coy.. I was just joking.. However, if you could get an air connector mounted on the antenna base somewhere and put pressure on it, then you could soap the antenna and look for bubbles. Once you get the antenna sealed, then perhaps you could charge it, or at least let it weep through the air fitting if it was positioned properly to act as a drain. Tight transmission lines are often pressurized with nitrogen. Microwave and cellular lines and antennae are often pressurized using dry air. A dehydrator, a compressor with a dryer, won't run out and need replacement like a nitrogen bottle would, and is more suited to leaky antenna systems. As long as you keep positive pressure on the line... no worrys... concerning water ingress anyway. Seriously, I don't know much about the Diamond X500 (dimensions, etc.), but if you can put an air fitting on it, then you can probably fix it.. Perhaps you can go to the auto parts or the tire store to get an air fitting. They pressurize tires, don't they? (Let me know if you spin balance it.. hi hi!)

Steve, Great thinking !! sounds like something a thinker, or engineer would come up with. I would even take this one under advisement. 73 AC0Y --- In Repeater-Builder@yahoogroups.com, "Steve Grantham" <[EMAIL PROTECTED]> wrote: > As long as we're engineering solutions... (hi hi!..)

OkayWhere did you drill the hole, at the base of the fiberglass or exactly where? I have this antenna, and have to make use of it, because it is what I have. 73 and Thanks AC0Y --- In Repeater-Builder@yahoogroups.com, "Brent" <[EMAIL PROTECTED]> wrote: > Good one Neil, or use it for a Rain gauge. j/k > I have tried to keep moisture out of those antenna and have had no luck, do > to them no having a good vent hole at the bottom to release any moisture.
